摘要
为了解决三容水箱系统的时滞和非线性等问题,提出了一种基于粗糙理论的故障诊断模型。在三容水箱故障诊断系统中运用了改进的布尔逻辑和RST相结合的离散化算法,对连续属性进行离散化,然后利用属性约简和规则提取算法,得到了决策规则,并用测试数据进行了验证。
n order to solve the shortcoming of time-delay and non-linear of the three-tank,this paper presents a diagnosis which based on rough set theory.It applies the improved discretization algorithm which combined and RST to discrete the continuous attributes.Then,it used the attributes reduction and rule extraction algorithm decision-making rules,the results show that the test data can prove the decision-making rules. model of fault Boolean logic to obtain the
